Diagnosis

Postpedicel with aristiform apex. Tergite 1 brown pruinose dorsally, yellowish brown pruinose laterally. Tergites 2–4 with distal margins yellowish brown pruinose. Tergite 5 with distal third gray-brown pruinose. Surstyli subsymmetrical, slightly longer than epandrium in dorsal view. Both surstyli more thickened medially than basally and apically, with inner and outer margins sinuous and apices slightly rounded and inward-directed; both surstyli with apices slightly rounded when seen in lateral view. Apex of phallic guide with an upper margin with a tuft of small setae basally, and translucid lobes lateroapically in lateral view. Phallus trifid, with ejaculatory ducts distinctly separated only in distal seventh.

Etymology

The species name refers to the type locality, Paramo of Santa Inés, Belmira, Colombia.

TERMINALIA ( Figs 46–52 ). Epandrium and surstyli dark brown ( Fig. 47 ). Surstyli ( Figs 47–49 ) subsymmetrical, and slightly longer than epandrium. Both surstyli more thickened medially than basally and apically, with inner and outer margins sinuous and apices slightly rounded and inward-directed; right surstylus slightly shorter and thicker than left in dorsal view ( Fig. 47 ); both surstyli with apices slightly rounded when seen in lateral view ( Figs 48–49 ). Gonopods subsymmetrical, right gonopod slightly thicker than left I ventral view ( Fig. 50 ). Apex of phallic guide stout, with apex hook-shaped, upper margin slightly curved upward, with a tuft of small setae basally, and a translucid lobe lateroapically in lateral view ( Fig. 51 ). Ejaculatory apodeme parasol-shaped ( Fig. 52 ). Phallus trifid, thin, with ducts distinctly separated only in distal seventh ( Fig. 51 ).

Female

Unknown.

Geographical distribution

Colombia (Antioquia, Boyacá) ( Fig. 53 ).

Habitat

The specimens were collected in the Páramo Santa Inés, with areas of very humid premontane forest of the Oriental and Central cordillera of Northwest Colombia and Santuario de Fauna y Flora Iguaque reserve, where the vegetation is composed of cloud Andean forests of the cordillera of Northeast Colombia.

Remarks

Based on males and due to the shape of the phallus, D. santainesensis sp. nov. ( Fig. 51 ) is similar in appearance to D. gibber sp. nov. ( Fig. 25 ) but differs from the latter in having both surstyli more thickened medially than basally and apically, with inner and outer margins sinuous, apices slightly rounded inward-directed; right surstylus slightly shorter and thicker than left in dorsal view ( Fig. 47 ) (vs both surstyli thickened basally and medially, thin apically with inner margins slightly straight, outer margins curved; right surstylus thicker than left, with apex truncated; left surstylus with apex rounded in D. gibber sp. nov. in dorsal view; Fig. 21 ); gonopods subsymmetrical ( Fig. 50 ) (vs gonopods asymmetrical; Fig. 24 ); upper margin of apex of phallic guide with a tuft of small setae basally in lateral view ( Fig. 51 ) (vs apex of phallic with a stout and rigid lobe dorsally in lateral view; Fig. 25 ).

Unidentified females of Dasydorylas

Twenty-four females of Dasydorylas , subdivided into nine morphospecies could not be associated with males. Future DNA-sequencing of these specimens likely will help with this association.
